To all'. whom it my concern: Y

Be it known that I, lioness H. Emmen ci tizen of the United States, residing' nt Sioux City, in the county of Woodiiu ry and Stute of Iown., (whose post-oilice address is Sioux City, lo\va,)heve invented n new nud useful Lubricating-Machine; and I do declare the foilowing to be n full, clear, and 'exact description of the sume, reference being had to the accompanying drawings, forming n. pnrt thereof.

My invention relates to devices used in the appiicntion of lubricntors to machinery, und is cspecialliT adapted to the purpose of applying graphite mixed with oil, or other similar lubricants, to the cylinders of steam-engines.

The object of my invention is to provide menus for automatically and eontinuousb7 lu' briceting the operntin g partsof the machinery from e. receptacle iirst supplied with the lubri outing material.

The invention comprises n liller frorri which the lubricant is supplied and a. lubricatingmachine which feeds the lubricant as required; end it consists in' the novelty of construction, nrrnngement, und combination of parts, as

will be horeinnfter specilicnlly described, und

pointed ont in the claims.

Reference is now had to the accom pnnying drawings, forming a part of this specilcntion, in which- Figure 1 is n view of liller or een containing the lubricant to be supplied to the lubricating-machine. Fig. 2 is e view of the sume kind of cnn, but provided with a dilerent form of cover. Fig. 3 is u. side view of machine, shown partly in section, used in the automatic application of the lubricnnt.

Fig. le is e. perspective View of used in the regulation of the supplI of liquid.

Referring now to the illustrations, in which like parte nre designntcd by similar letters of reference, A is n killer or can from which the lient lubricant is supplied to the lubricntingmuchine es it lbecomes exhausted in use. it. is mode of any suitable niaterinl and size und Yis suppiied with e screw-top cover 'lhe cover has n. round opening in the center provided with screw-threads, und through said opening passes a rod, C, having screw-threads corresponding to the threads in scid opening. The upper end of the rod has n crank D. To the iower ond is secured a heed E, provided on the lower sido with u washer F, secured-to Y the head by ineens of the follower E' and screw G, nil ofivliich constitute e piunger to force the lubricant H out of the iillcr. At the side of the liller near the bottoni Vis a. rouu opening A', littcd iizith e'pipe B", having screw-threadsto which is attached ehese B'", which when the lubricant is to he forced from the liller into the cylinder or receptacle of the lubricating-machine is attached to n pipe connecting therewith.' forced out of the iiller through the hose und into seid cylinder by turning the crnnk l) an pressingthe plunger down upon the lubricant which socks escape through the hose.

In Fig. 2 is shown the [illcr with u. different form of cover. Instead of being screwed on the cover B' is fitted on one side with u hinge a, while on the other side is a spring af, provided with e lug c", adapted to lit e. groove a'. When required to replenish the lilier with lubricant, the plunger is raised to the top of the een, when the cover und all een be turned beck, as seen by the dotted lines, und the lubricant emptied in through the open top. in Figs. 3 und i is shown the machine for forcing the luhricnnt into the cylinder of the engine or other machinery after being supplied from the liller. It consists, llrst, of n cylinder or cnn I, supported upon suitable framework t L; A pipe c, to which the hose B'" may be attached, lends into the cylinder 1, and through this pipo the lubricant is sup- The lubricant is'- del.

pliedl to said cylinder from the filler as it becomes exhausted from the machine. Near the upper end of the pipec is a valve c', which is to be closed after thclubricant is supplied. The pipe c" leads oli from the pipe c to the steam-cylinder or other machinery necessary to be lubricated, while the check-valve t prevents any return of the lubricant. The lubricant is supplied from the cylinder I to the machinery in the following manner: Fitting tightly within the cylinder is a double plunger 1' I', consisting of the heads 1I i, washers 11' t", followers "11", and screwsz'm 1"", facing in opposite directions. On one side of 4the plunger is the lubricant H, and on the other side is oil, water, or other suitable liquid K', pumped into the' cylinder for the purpose of forcing the lubricant, by means of the double plunger, out at the opposite end through the pipe c". The cup K, cntainingthe liquid K', communicates with the cylinder I by means of the pipe d. The natural tendency of the liquid to seek its level is assisted bythe pumprod L, operating in the pump barrel or branch pipe d'."V The pump is operated in the following manner: A shaft e, parallel with the branch piped', is adapted to revolve, by means presently described, inv suitable bearings on the framework. Secured to the hub c', which is keyed upon the shaft, is a wheel` e", set at an angle of nearly.forty`tive degrees to the shaft and pump-rod, 'andas the wheel revolves with theehaft it operates against ashoulder L' on one side of the outer end of the plunger, pushing it inward and against the liquid in the pipe and forcing the liquid up in the pipe d and into the cylinder. 'A thumb-screw L" in the outer end of thc -pump-rod may be used to regulate the length of the stroke, and a brace supports the To avoid leakage. the outerend of the branch pipeiis provided with theusual packing fand retaining-nutf'. 0n opposite sides ofthe entrance of the'pipe d' to the piped arecheck-valvesd and d' which prevent the backward iiow of the liquid. At the opening of the cup K into the pipe d is a valve g, which regulates the su pply of the liquid in the pipe d by means of the ioat g' in the stand-pipe It. The usual jointed rod g", pivotally attached at theI point g" to the pipe d, connects the valve with the float. A glass tube g* is titted in the pipe duear the upper end, where the pipe enters the cup,

and there being a round opening in the pipe opposite the tube, as seen more clearly in F|g.11, the supply of liquid may be observed through the glass. A slot g" is made in the tube to permit the operation o f the lever g",' -and a corresponding slot is made in the pipe d.4 The washers g" at bothends of thetube hold it firmly in place and protect it from breakage. A seat g', having the guide-posts g! g, is provided for the valve g., 4Vlfhere the pipe d turns to enter the cylinder I, another tube.

pipe, M, branches ofi and enters the cup K at the top of said cup. At the lower end of the pipe M is a valve M', which is always to be closed except when the lubricant is being supplied to theY cylinder by means of the h'ller. When the illcr is connected with thc cylinder by means of the hose, the plunger E screwed down upon the lubricant, and the latter forced into the cylinder I, the plunger I', which when the lubricant is exhausted is located in the left end of the cylinder and the rest of the cylinder [illed with the liquid, is

pushed to the right and forces the liquid to ilow back into the pipe d.' The valve d'" stops the downward il'ow, and the valve M' being open the liquid seeks an outlet through the pipe M into the 4cup K. 'lhe liquid can thus be repeatedly utilized, but as it becomes exhausted can he supplied to the cup through the opening l, having the cover Z'.

In the use as a lubricant of graphite mixed with oil itis necessarythat it be kept constantly agitatedA to prevent settling of the .graphite to the bottom. This is provided for by means of a cogged wheel N, secured to the right end of the cylinder I and adapted to mesh witha worm-wheel O, lirmly secured to the revolving shaft c, which in connection with the worm-'wheel and cogged wheel keeps the cylinder constantly turning, thus agitating the lubricant. ...This shaft is revolved by means of a ratchet-wheel I?, firmly secured to the shaft near the left end, a rim-- wheel P' encircling said ratchet-wheel and adapted to turn on the shaft as an axis, the pawls p p, attached to the rim-wheel P', adapt- 'ed to engage the ratchet-wheel, thearm R,

secured to the rim-wheel, and the connectingyrod S, pivotally secured tothe outer end of the arm and adapted forconnection at its opposite end Vwith an oscillating part of the machinery with which the lubricating-machine is connected. A spring s, controlled by a coil-spring s' and adapted for regulation by a thumb-screw s", acts as a brake upon the ratchet-wheel and steadies it in its revolutions, .As the cylinder revolves and the pipes c and (l, which enter the cylinder, are stationary, joints with suitable packing are provided where said pipes enter thecylindcr, and the pipcs'bcing supported by the framework furnish an axis on which the cylinder turns.

As will be seen, the construction just de' `scribed causes the cylinder containing the lubricant to revolveandat the saine time operates the pump, which forces the liquid into the cylinder and presses out the lubricant as needed for the machinery.

The plunger-heads 111', Fig. 3, are 'somewhat smaller than the cylinder and permit a quantity of air to enter around the plunger-heads through the tube T, Whichcnters the cylinder through the pipe c and the opening T' in the plunger-heads, which communicates with said By maintaining atmospheric pressure IOO 'rasees between the plunger-bends the rpressure of the liquid will force the pecking of the plungerlieads into more intimate contact with the intcrior oi the cylinder, and thereby .prevent lealmge. A

The joint-s in the pipesc and d, where there is liability of leakage of the lubricant, are protected with suitable packing n n. and the paci:- ing glands' und bolts lv -r und 'm mrcspectively. 1n Figs. g5 and 6 is shown n means for working the pump when the speed of the operatingshaft is too high to be applied in the manner previously described. 'lhe hub c' and the wheel c" are removed and another hub,Y, having secured to it n worm-wheel Y', is firmly secured to the shaft in its place. Instead of the plunger-rod with shoulder and thumbscrew e piston-rod y is pivotally secured to the outer end oi' the plunger-rod and at the opposite end pivotnlly secured, by means of the thumb-screw 2", to one of the bearings Z' in the cogged drive-wheel X, which meshes with the worm-wheel Y. The drive-wheel revolves upon an axis fr, supported by ebrnce` s, extending outward from the framework. 1l desired to regulate the stroke of the rod more closely then can be done inthe bearings, the thnmbscrew may beset in the slot-.em in the wheel.
